Gastrointestinal MotilitySymptoms of IBS are influenced by changes in the way the bowel works, including spasms of the muscle in the wall of the intestine. The muscle spasms are equivalent to the cramps commonly felt in the calf. As previously described, muscle activity normally moves waste material through the digestive system in rhythmic waves (peristalsis); in IBS the movement may be irregular and uncoordinated. |
